To understand nonylphenol (NP) contamination in the northeast coastal environment in China, NP was determined in 19 sediment and 20 bivalve samples collected during November 2005. NP was identified in all sediment samples in the range of 8.8 to 1.0 x 10(3) ng/g dw (dry weight), with an average of 0.12 x 10(3) ng/g dw. Most of the bivalve samples (oysters and mussels) contained detectable amount...

The coastal region of Chabahar Gulf with 1113.7km2 area has been located in the southeast of Iran. In this research, satellite images of ETM+ (2004) were used in order to zoning of sedimentary environments in this Gulf. Methodology of this research was baesd on synthesis of supervised and unsupervised classifications in GIS and ENVI softwares. Based on studies and calculat...

France is geographically located in a central maritime position within the European Union (EU). Consequently, the experience gained and the solutions proposed in France may be of interest within a much wider geographical and institutional framework. The EU directives and regulations and the international treaties and conventions bind it. Among the ‘tools’ for environmental protection and manage...

The natural environment is unequivocally the life support for all human systems. Far for being a luxury available only to those who can afford it, successful environmental management will increasingly become the basis for the success or failure of the economics and social systems of entire countries. In the last two decades, concern has been expressed about possible effects of climate change in...

The United States faces the major dilemma of meeting energy demands while simultaneously reducing the environmental consequences of energy production. How we resolve this dilemma has implications for the nation’s economy, environment and energy security. One of the many methods proposed for addressing this challenge is using the wind resource available off the coast of the United States to gene...

Coastal area represents one of the more delicate and complex relation between natural environment and human activities. Remote sensing, offering considerable understanding of the temporal dynamics of bio-physical factors at different scale, represents a solution for monitoring the ecosystem. In particular marine phenomena, i.e. Sea Surface Temperature, chlorophyll concentration etc. can be rela...

The structural features of humic acid (HA) at the sediment surface of the tideland at the Hayatsuegawa-river mouth at the Ariake Sea were investigated for the utilization of HA toward an environmental indicator of the features of the river basin and coastal region. 1H NMR analysis revealed a high-content hydrocarbon residue with a similar type of terrigenous HA. Direct and methylation-pyrolysis...

Integrated management is a central theme of Australia’s Oceans Policy (AOP). Improving integration across sectors and jurisdictions has been identified in a number of Australian initiatives in coastal and marine policy developed in the past decade. These initiatives include the Regional Marine Planning process under AOP undertaken in 2000–02 and commitments to a National Coastal Policy made in ...

An annual seasonal cycle of composition of a bacterioplankton community in an oligotrophic coastal system was studied by denaturing gradient gel electrophoresis (DGGE) using five different primer sets. Analysis of DGGE fingerprints showed that primer set 357fGC-907rM grouped samples according to seasons. Additionally, we used the set of 16S rRNA genes archived in the RDPII database to check the...

BACKGROUND Understanding the relationship between environment and genetics requires the integration of knowledge on the demographic behavior of natural populations. However, the demographic performance and genetic composition of Arabidopsis thaliana populations in the species' native environments remain largely uncharacterized. This information, in combination with the advances on the study of ...
